Possibly because of the Canadian heritage of the company, most people seem to think Seagram's 7 is a Candian Whisky, but it's an American blended whiskey. American blended whiskey must contain 20% straight whiskey and the rest can be neutral spirits (i.e. vodka), coloring and flavoring. The distillery isn't disclosed but for years the whiskey was distilled at LDI, the former Seagram's distillery in Indiana.
The nose is very vaguely whiskey smelling. That's about it. The palate is just foul. It's sweet and only tastes very vaguely of whiskey. It's sort of a generic whiskey taste, though it's more spicy than sweet so tasting blind I might have guessed that it was a really bad rye, but it doesn't have any really distinctive qualities. The major flavor is just alcohol. The finish is like the taste in your mouth after a bad hangover. There's just no reason to drink this.
